Summa Silver Corp. provided assay results from its final two drill holes completed during the winter drill program at the high-grade silver-gold Mogollon Project, New Mexico (the "Mogollon Project"). Key Highlights.

New Vein-Splay Drilled: This intersec on is from a previously undrilled splay of the Queen Vein and opens new explora on poten all into areas east of the main strand of vein. size and Scale: This drill program successfully showed that strong mineraliza on exists along at least 2 km of the Queen Vein system. Addi onal Upside: Systema follow up drilling is required on the Queen Vein and beyond which is expected to delineate significant zones of high-grade mineraliza on.

The first hole of the program (MOG23-20) tested the South Queen target, located between the Deadwood and Eberle mines, and intersected 393 g/t silver equivalent (3.9 g/t Au and 64 g/t Ag) over 7.4 m including 2,735 g/t silver equivalent (28.6 g/t Au and 320 g/t Ag) over 0.5 m. Holes MOG23-21 and MOG24-22 tested the Eberle target, centered on the structural intersec on between the east-west trending Maud S Vein and the Queen Vein system. The mine, developed on three levels, produced 10,000 tonnes of ore (pre-1916)1, where more recent underground channel samples assayed up to 5,173 g/t silver equivalent. Hole MOG23-21 was collared 300 m southwest of the Eberle mine portal in the footwall of the Queen Vein.

Based on comprehensive modelling of all known veins in the district from historical reports and mapping, the veins intersected in hole MOG21-21 may represent new vein discoveries in the hanging wall to the Queen Vein or poten al structural offsets of the eastern strand of the broader Queen Vein system. Further drilling, focused on inves Ga ng poten al structural offsets and/or cross faults (e.g., MOG24-22) or parallel veins, is clearly warranted at the Eberle target to be er define the structural controls and orienta ons of all vein-sets in the complex Queen Vein system. Results from hole MOG23-21 strongly supports the high-prospec vity of the Queen Vein system south of the Consolidated Mine target, located 1.2 km to the north.
